Ecrou de Cartier Guide: Rings, Bracelets, Necklaces and Sizes
Cartier made its name with the Love bracelet and its screw motif. The Écrou line takes a different idea from the workshop: the humble nut. The result is a smooth, hexagonal jewel that looks modern, simple and very wearable.
This Ecrou de Cartier guide explains the collection in plain words. You will see the main pieces, the gold colours, how to pick the right size, and what to check on a pre-owned piece. It is written for shoppers in Dubai and across the UAE.

Ecrou de Cartier Guide: What the Nut-Shaped Collection Is
Écrou is the French word for a nut, the small hexagonal part that holds a bolt. Cartier turned that everyday shape into fine jewellery. The idea sits close to the brand’s love of industrial details, which you can also see in the Cartier Love collection.
Three things define the look:
- The hexagon: a six-sided nut shape, clean and sculptural.
- Smooth gold: polished surfaces with no busy decoration.
- Unisex style: the pieces in our store are listed as unisex, so they suit any wrist.
This Ecrou de Cartier guide treats the line as one family. Bracelets are the easiest pieces to find, while rings and necklaces follow the same nut motif.
Ecrou de Cartier Bracelet: Models and Fit
The bracelet is the star of the range. It is a slim, rigid band with the nut shape as its signature. It sits close to the wrist, so it works alone or in a stack.
Our store currently lists three pieces in the Ecrou de Cartier collection. Here is how they compare:
| Reference | Gold | Size | Condition | Papers |
|---|---|---|---|---|
| CRB6067118 | 18k yellow gold | 18 (width 5 mm) | Pre-owned, like new | Box and Cartier service paper |
| CRB6049615 | 18k white gold | 15 | Pre-owned, like new | Box and bill (2017) |
| B6067117 | 18k yellow gold | 18 | Pre-owned, like new | Box and polish paper |
Note the two sizes, 15 and 18. A small number means a snug bracelet for a slim wrist, and a bigger number means more room. If you are unsure, read the next section before you choose.
Every piece in the table is pre-owned and listed with its reference number. That makes it easy to compare with the Cartier boutique details. This part of the Ecrou de Cartier guide matters most if you plan to wear the bracelet every day.
Ecrou de Cartier Ring and Necklace: What to Expect
Many shoppers search for an Ecrou de Cartier ring or necklace as well. Both follow the same idea as the bracelet: a nut-shaped form in smooth gold, kept simple so it goes with everything.
Availability changes often, because pre-owned stock is one of a kind. Today our Ecrou page shows bracelets only. Ask our team if you want a ring or a necklace, and we will tell you what we can source.
A ring works best when it is worn with plain bands, while a necklace adds a small point of interest at the collarbone. If you already own a bracelet, a matching ring is an easy way to build a set.
Gold Colours in the Ecrou Range
Cartier works with several gold colours. In our store you will find two of them:
- 18k yellow gold: warm, classic and the most familiar Cartier look.
- 18k white gold: cool, modern and quiet. It pairs well with a steel or platinum watch.
Pick the colour that matches what you wear every day. If your watch and rings are yellow gold, stay with yellow. If they are silver-toned, white gold keeps the look consistent. Mixing colours is also fine when the pieces are simple.
How to Choose the Right Size
Size is where most buyers hesitate. Use the steps below, and keep them handy when you read this Ecrou de Cartier guide again.
Bracelet size
- Measure your wrist with a soft tape just above the wrist bone.
- Compare the number with the size on the listing, such as 15 or 18.
- Remember that a rigid bracelet has to pass over your hand, so it should not be too tight.
- If you are between sizes, ask for advice or try the piece on.
Ring size
Cartier ring sizes follow the European system. The number is based on the inner circumference of the ring in millimetres. You can read more about how ring sizes work. Measure the finger at the end of the day, when it is at its largest.
Tip: try a rigid bracelet on before you decide. The same number can feel different from one design to the next, and a good fit makes the difference between a jewel you love and one you leave in the box.
Buying a Pre-owned Ecrou: What to Check
Pre-owned Cartier is a smart way to enter the brand. The pieces above are all listed as like new. Still, a few checks protect you:
- Confirm the reference number and the gold purity on the listing.
- Ask for the box and any papers, such as the bill or service paper.
- Look closely at the surface for deep scratches, because smooth gold shows marks.
- Check that the clasp or opening mechanism works cleanly.
- Buy from a seller that guarantees authenticity in writing.
Our listings state that authenticity is guaranteed by Elegance Times. You can also compare the collection with our wider range of Cartier jewelry to see how the Écrou fits beside Love and other lines.
You can browse every piece on the Ecrou de Cartier page and open each product to see its photos and details.
Caring for Your Ecrou Jewellery
Smooth gold is easy to look after. A few habits keep it bright:
- Wipe it with a soft cloth after wearing.
- Store it in a pouch, away from harder pieces that can scratch it.
- Take it off for sport, swimming and heavy cleaning.
- Ask a jeweller to check the clasp from time to time.
Ecrou de Cartier Guide: Frequently Asked Questions
What does Écrou mean in Écrou de Cartier?
Écrou is the French word for a nut, the small hexagonal part that holds a bolt. Cartier used the shape as the theme of this jewellery line. The nut form gives the pieces their smooth, geometric look, and it links the line to the brand’s taste for industrial details.
What is an Ecrou de Cartier bracelet?
It is a slim, rigid gold bracelet built around the nut motif. It sits close to the wrist and can be worn alone or with other bracelets. The pieces in our store are listed as unisex, in 18k yellow or white gold, with sizes such as 15 and 18.
Which size should I choose for an Ecrou de Cartier bracelet?
Measure your wrist just above the wrist bone and compare it with the size on the listing. Our pieces come in sizes 15 and 18. Because the bracelet is rigid and must slide over the hand, avoid a size that is too tight, and try it on if possible.
Does Ecrou de Cartier come in yellow and white gold?
Yes. In our store, the pieces are made in 18k yellow gold and 18k white gold. Yellow gold gives a warm, classic look, while white gold looks cooler and more modern. Choose the colour that matches the watch and jewellery you already wear every day.
Is there an Ecrou de Cartier ring or necklace?
The collection follows the same nut-shaped design across several piece types, including rings and necklaces. Availability changes because pre-owned stock is unique, and our Ecrou page currently shows bracelets. Contact our team if you want a ring or a necklace and we will check what we can source.
Is a pre-owned Ecrou de Cartier worth buying?
Yes, when the seller is reliable. Check the reference, the gold purity, the condition and the papers. All three pieces in our store are listed as pre-owned in like new condition with box and papers, and our listings state that authenticity is guaranteed by Elegance Times.
